Sending email in functional test times out

I’m writing a functional test to see if an email was generated from a
particular action. The action of course sends an email at some
point…but the test says it times out.
config.action_mailer.delivery_method is set to :test in
config/environments/test.rb, not sure why it would be ignoring that.
If I take out my email config from environment.rb, the test runs fine.
Here’s the exception:
